Part Number: LM2917-N Hi,
I intend to use LM2917 to read RPM of motorbike on an MCU by reading analog voltage by following circuit.
I want to remove the meter from this reference diagram and read the RPM on any MCU by reading analog voltage. From which…
Part Number: LM2917-N Hi,
Just to be double sure some guidance is needed to validate the circuit as much help is not available. This tachometer and speedometer would be for motorbikes only. For speedometer hall effect sensor is used and for tachometer…
Part Number: LM2917-N I'm using the LM2917 in 14 pins package, I can't make it work, maybe you can draw me the correct schematics for a pulse from 0 to 2.3Khz 0-5v
that I would lkie to measure using a 3.3V A2D, I'm currently using 24V as input…
Part Number: LM2907-N Hi
I'm using the LM2907 14 pins. In page 4 of AN162 it says: "The voltage appearing at pin 2 will swing between two values which are approximately 1/4 (VCC) - VBE and 3/4 (VCC) - VBE" my first question is how can I figure…
Part Number: LM2917-N Hi. Page 15 of the datasheet shows the output response time to a change in Freq at around 250ms with the stated component values. Is it possible to decrease the response time to below 30ms? I calculate Vripple to be 10mVp-p @ Fin…
Part Number: LM2917-N Hi,
My customer has the following question about the LM2917-N.
1. What are the frequency limits (highest and lowest)?
2. What is the output type, AC or DC?
3. If AC output. The Input frequemcy=out frequency? What is the output type…
Part Number: LM2917-N Other Parts Discussed in Thread: TMAG5111 , OPA191 Hi,
Any design suggestions to determine the acceleration out of the LM2917? Basically a tachometer, a hall affect sensor (TMAG5111) input to the LM2917, input frequency range from 0…
Part Number: LM2917-N Other Parts Discussed in Thread: LM2907-N I'm considering F-Vconverter oring circuit.
However, the attached circuit does not work well, what is the cause? Input:J23.3-4(open collector)×3 Fan:9LG1224P1G001(San Ace)
Part Number: LM2917-N Hi team,
I was wondering why a customer might prefer the 14 pin version of this part compared to the 8, given the 14 pin has 4 NC pins. Other than size or cost. Is it a simpler design with more pins? Are there any other benefits…
Part Number: LM2917-N Other Parts Discussed in Thread: LM2907-N Hi Team, May we know the rated max junction temperature for LM2917-N ? Thanks in advance! Kind Regards, Jejomar
